928 X-Pipe on Ebay

I added 20hp at the wheels with an X-pipe, on a non-cat car. On a car with cats you can gain even more as after 20 years the factory cats tend to be plugged with carbon and are restrictive.
RMB is for people who like to sound like they're going fast even when they're not; it doesn't add power. I like it the other way around...

I looked at this also. But since I would also need to buy cats and have them shipped; I figured anything over $250 was probably a no go. I think I'll just get all new.
